I've got an iBook with a knackered hard drive but no idea what drive to replace it with? I found instructions on how to change the hard drive elsewhere on the forums but need to find out what will fit in before I order it or start taking the laptop apart. It was a 30GB item in an iBook bought from Apple in August '03 (700mhz 12"part #Z05001750 model A1005) The iBook is now being replaced as my main PC so I'm looking for an inexpensive hard drive that only needs to be say 10GB. What should I be looking for? Any recomendations? And finally once I install it is loading the OS etc onto it a big deal or simple throw in a CD and follow the instructions? Any help would be great.
